Woman with sword on a moonlit beach in dramatic backlight

A young woman standing barefoot on a wet sandy beach at night, soft feminine face with delicate features, fair pale skin, dark wavy messy hair falling around her face and shoulders, eyes cast downward in a quiet contemplative expression, slightly parted lips, wearing a lightweight flowing white off-shoulder dress with soft fabric details, holding a large ornate silver medieval sword high above her head with both hands, strong dramatic backlighting from a bright starburst light source behind her creating intense lens flare and rim light on her face and body, dark deep blue night sky, ocean waves, wet sand reflections, moody cinematic atmosphere, ethereal and mysterious fantasy vibe, highly detailed face, photorealistic, 8k
